Ajax Enabled Gridview using JavaScript in ASP.NET

Before explaining the article, I would like to thank all readers who read my article and voted for it. Your appreciation for my article gives me strength to write more good articles. Hope in future I will get your valuable comments and suggestions. Now I won't waste your time and come back to the topic. I have written this article on 'Ajax Enabled Gridview Using JavaScript in ASP.NET'. In this article, I will show you how to make a Gridview using a simple HTML table, JavaScript and XML HTTP for Ajax call without using any ASP.NET control.

This article shows 2 common tasks with the ASP.NET GridView: Binding a List (generic) of objects as DataSource and on clicking a row, getting the values of the selected row by a javascript function. In the example a List with User-objects is displayed. On clicking a row containing the data of a User-object, the Id of the object is used to get the address of the user by an Ajax-call and display it in a details-field.

In the previous article GridView Select Multiple Rows you learnt the multiple row selection in GridView control. Here you will get the C# code sample to select all the gridview rows using single checkbox server control. You can highlight the selected rows with different color and Font state Bold. If you want to use the selection values on different ASP.Net

To enable the GridView Paging and Sorting to update the GridView Data without refreshing the ASP.Net web page AJAX Extension controls are used. UpdatePanel is used to hold the GridView control that triggers the events for the controls placed inside it. By Default UpdatePanel triggers the asynchronous postbacks for its child controls.

I've posted an update to this post to apply on demand loading of Details data using ASP.NET AJAX PageMethods. I'm demonstrating the usage if CollapsiblePanelExtender client events on the new post. Check it out.

I admit, Matt Berseth is really inspiring me! Few days ago I pass through 2 of his great posts:

.Surrounding your Data Table and Dialog Controls with ComponentArt Styled Panels .Building a Grouping Grid with the ASP.NET 3.5 LinqDataSource and ListView Controls The first one is pure design tips one which I used for making good presentation of my demo here. The 2nd post is actually the idea.

One of the pain points with developing AJAX, JavaScript, JQuery, and other client-side behaviors is that JavaScript doesn't allow for cross domain request for pulling content. For example, JavaScript code on www.johnchapman.name could not pull content

the text says "When you configure an AJAX-enabled ASP.NET Web site, use only the default value of UseCookies for the cookieless attribute. Settings that use cookies encoded in the URL are not supported by the ASP.NET AJAX client script libraries."

I'm using Ajax so are there any ideas what I can do about this problem.

One month ago I've had very nice conversation with a asp.net forum member asking about issue regarding calculation of GridView textboxes total using JavaScript. The main thing was to allow user to manually write values in the text boxes (placed inside GridView column) and if the value has changed automatically to perform calculation on client side.

At the end of the conversation, we came up to two solutions. The first solution was using plain JavaScript, but since I thought it was not so robust, and in order to make it more robust we would need to write few more functions. Therefore, I have simply proposed another solution using JQuery which came up much better, more robust with less code.

In this blog post I will show both of the solutions and will provide step by step explanation on how we did that.

I'm a rookie with Javascript/Ajax and I was hoping someone could provide an code example or advice of the following scenario:

1. User clicks a button on the view

2. Display a message "Waiting to be processed". (Currently using Javascript)

3. Execute the action method to retrieve some data. (Call made from the Javascript)

4. Return the same view.

5. Open up a new browser window with a URL that was obtained from the action method.

How do I open a new browser window automatically after the action method is complete? I was previously making the following call (Process.Start(http://www.yahoo.com);) in the action method but I'm running into issues with it. I'd like to use Javascript/Ajax.

If it helps this the javascript code that is run when the button is clicked:

I have a website where anonymous access is disabled but I want to user an ajax-enabled WCF service. Configuring the service's binding security to use "TransportCredentialOnly" with clientCredentialType="Windows" seems like the obvious thing to do; indeed,
many posts in various places suggest this approach. Unfortunately, however, it doesn't work. I always get the error "Security settings for this service require 'Anonymous' Authentication but it is not enabled for the IIS application that hosts this service."
How can I configure the service to function correctly. I'm running IIS 7.5 with .Net framework 4.0.
Thanks.
